2011-11-20Btrfs: sectorsize align offsets in fiemapJosef Bacik1-1/+4
We've been hitting BUG()'s in btrfs_cont_expand and btrfs_fallocate and anywhere else that calls btrfs_get_extent while running xfstests 13 in a loop. This is because fiemap is calling btrfs_get_extent with non-sectorsize aligned offsets, which will end up adding mappings that are not sectorsize aligned, which will cause problems in some cases for subsequent calls to btrfs_get_extent for similar areas that are sectorsize aligned. With this patch I ran xfstests 13 in a loop for a couple of hours and didn't hit the problem that I could previously hit in at most 20 minutes. Thanks, Signed-off-by: Josef Bacik <[email protected]>

2011-11-20Btrfs: wait on caching if we're loading the free space cacheJosef Bacik2-41/+81
We've been hitting panics when running xfstest 13 in a loop for long periods of time. And actually this problem has always existed so we've been hitting these things randomly for a while. Basically what happens is we get a thread coming into the allocator and reading the space cache off of disk and adding the entries to the free space cache as we go. Then we get another thread that comes in and tries to allocate from that block group. Since block_group->cached != BTRFS_CACHE_NO it goes ahead and tries to do the allocation. We do this because if we're doing the old slow way of caching we don't want to hold people up and wait for everything to finish. The problem with this is we could end up discarding the space cache at some arbitrary point in the future, which means we could very well end up allocating space that is either bad, or when the real caching happens it could end up thinking the space isn't in use when it really is and cause all sorts of other problems. The solution is to add a new flag to indicate we are loading the free space cache from disk, and always try to cache the block group if cache->cached != BTRFS_CACHE_FINISHED. That way if we are loading the space cache anybody else who tries to allocate from the block group will have to wait until it's finished to make sure it completes successfully.

2011-11-20Btrfs: avoid unnecessary bitmap search for cluster setupLi Zefan1-38/+4
setup_cluster_no_bitmap() searches all the extents and bitmaps starting from offset.

2011-11-20Btrfs: fix to search one more bitmap for cluster setupLi Zefan1-0/+12
Suppose there are two bitmaps [0, 256], [256, 512] and one extent [100, 120] in the free space cache, and we want to setup a cluster with offset=100, bytes=50. In this case, there will be only one bitmap [256, 512] in the temporary bitmaps list, and then setup_cluster_bitmap() won't search bitmap [0, 256]. The cause is, the list is constructed in setup_cluster_no_bitmap(), and only bitmaps with bitmap_entry->offset >= offset will be added into the list, and the very bitmap that convers offset has bitmap_entry->offset <= offset.

2011-11-20Btrfs: fix barrier flushesChris Mason2-17/+134
When btrfs is writing the super blocks, it send barrier flushes to make sure writeback caching drives get all the metadata on disk in the right order. But, we have two bugs in the way these are sent down. When doing full commits (not via the tree log), we are sending the barrier down before the last super when it should be going down before the first. In multi-device setups, we should be waiting for the barriers to complete on all devices before writing any of the supers. Both of these bugs can cause corruptions on power failures. We fix it with some new code to send down empty barriers to all devices before writing the first super. Alexandre Oliva found the multi-device bug. Arne Jansen did the async barrier loop.

2011-11-20KVM guest: prevent tracing recursion with kvmclockAvi Kivity1-2/+3
Prevent tracing of preempt_disable() in get_cpu_var() in kvm_clock_read(). When CONFIG_DEBUG_PREEMPT is enabled, preempt_disable/enable() are traced and this causes the function_graph tracer to go into an infinite recursion. By open coding the preempt_disable() around the get_cpu_var(), we can use the notrace version which prevents preempt_disable/enable() from being traced and prevents the recursion. Based on a similar patch for Xen from Jeremy Fitzhardinge. Tested-by: Gleb Natapov <[email protected]> Acked-by: Steven Rostedt <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2011-11-20drm/radeon/kms: add a CS ioctl flag not to rewrite tiling flags in the CSMarek Olšák7-98/+135
This adds a new optional chunk to the CS ioctl that specifies optional flags to the CS parser. Why this is useful is explained below. Note that some regs no longer need the NOP relocation packet if this feature is enabled. Tested on r300g and r600g with this flag disabled and enabled. Assume there are two contexts sharing the same mipmapped tiled texture. One context wants to render into the first mipmap and the other one wants to render into the last mipmap. As you probably know, the hardware has a MACRO_SWITCH feature, which turns off macro tiling for small mipmaps, but that only applies to samplers. (at least on r300-r500, though later hardware likely behaves the same) So we want to just re-set the tiling flags before rendering (writing packets), right? ... No. The contexts run in parallel, so they may set the tiling flags simultaneously and then fire their command streams also simultaneously. The last one setting the flags wins, the other one loses. Another problem is when one context wants to render into the first and the last mipmap in one CS. Impossible. It must flush before changing tiling flags and do the rendering into the smaller mipmaps in another CS. Yet another problem is that writing copy_blit in userspace would be a mess involving re-setting tiling flags to please the kernel, and causing races with other contexts at the same time. The only way out of this is to send tiling flags with each CS, ideally with each relocation. But we already do that through the registers. So let's just use what we have in the registers.

2011-11-19fs/minix: Verify bitmap block counts before mountingJosh Boyer3-10/+42
Newer versions of MINIX can create filesystems that allocate an extra bitmap block. Mounting of this succeeds, but doing a statfs call will result in an oops in count_free because of a negative number being used for the bh index. Avoid this by verifying the number of allocated blocks at mount time, erroring out if there are not enough and make statfs ignore the extras if there are too many.

2011-11-19hugetlb: remove dummy definitions of HPAGE_MASK and HPAGE_SIZEDavid Rientjes1-5/+0
Dummy, non-zero definitions for HPAGE_MASK and HPAGE_SIZE were added in 51c6f666fceb ("mm: ZAP_BLOCK causes redundant work") to avoid a divide by zero in generic kernel code. That code has since been removed, but probably should never have been added in the first place: we don't want HPAGE_SIZE to act like PAGE_SIZE for code that is working with hugepages, for example, when the dependency on CONFIG_HUGETLB_PAGE has not been fulfilled. Because hugepage size can differ from architecture to architecture, each is required to have their own definitions for both HPAGE_MASK and HPAGE_SIZE. This is always done in arch/*/include/asm/page.h. So, just remove the dummy and dangerous definitions since they are no longer needed and reveals the correct dependencies. Tested on architectures using the definitions with allyesconfig: x86 (even with thp), hppa, mips, powerpc, s390, sh3, sh4, sparc, and sparc64, and with defconfig on ia64.

Commit 2aede851ddf08666f68ffc17be446420e9d2a056 (PM / Hibernate: Freeze kernel threads after preallocating memory) postponed the freezing of kernel threads to after preallocating memory for hibernation. But while doing that, the hibernation test TEST_FREEZER and the test mode HIBERNATION_TESTPROC were not moved accordingly. As a result, when using these test modes, it only goes upto the freezing of userspace and exits, when in fact it should go till the complete end of task freezing stage, namely the freezing of kernel threads as well. So, move these points of exit to appropriate places so that freezing of kernel threads is also tested while using these test harnesses. Signed-off-by: Srivatsa S.

commit f39925dbde77 (ipv4: Cache learned redirect information in inetpeer.) introduced a regression in ICMP redirect handling. It assumed ipv4_dst_check() would be called because all possible routes were attached to the inetpeer we modify in ip_rt_redirect(), but thats not true. commit 7cc9150ebe (route: fix ICMP redirect validation) tried to fix this but solution was not complete. (It fixed only one route) So we must lookup existing routes (including different TOS values) and call check_peer_redir() on them.

I will no longer be maintaining XFS for SGI. Ben Myers ([email protected]) has agreed to be the primary maintainer for XFS in my place. I will continue to be able to push commits to the SGI XFS tree if required. As such I will continue to be a designated XFS maintainer, but plan to serve in more of a backup role.

2011-11-18ping: dont increment ICMP_MIB_INERRORSEric Dumazet1-2/+0
ping module incorrectly increments ICMP_MIB_INERRORS if feeded with a frame not belonging to its own sockets. RFC 2011 states that ICMP_MIB_INERRORS should count "the number of ICMP messages which the entiry received but determined as having ICMP-specific errors (bad ICMP checksums, bad length, etc.)."

2011-11-18USB: Fix Corruption issue in USB ftdi driver ftdi_sio.cAndrew Worsley1-3/+11
Fix for ftdi_set_termios() glitching output ftdi_set_termios() is constantly setting the baud rate, data bits and parity unnecessarily on every call, . When called while characters are being transmitted can cause the FTDI chip to corrupt the serial port bit stream output by stalling the output half a bit during the output of a character. Simple fix by skipping this setting if the baud rate/data bits/parity are unchanged. Signed-off-by: Andrew Worsley <[email protected]> Cc: stable <[email protected]> ---- I had a brief run with strace on the getty and it was doing ioctl()s on each call but it didn't look relavant to the problem. I think the issue is that XON/XOFF flow control was being implmented via hardware - for the ixoff to allow the user to use XON/XOFF to control output. Unfortunately it would send 3 Control URBs updating all of the settings after each piece of input I am trying to work around the issue of gmail messing with the tab/spacing by submitting via SMTP via gmail which I believe should fix the issue. The patch is against v3.2-rc2 and compiles - but no additional testing in this kernel has been done. Thanks Andrew Signed-off-by: Greg Kroah-Hartman <[email protected]>

2011-11-18OHCI: final fix for NVIDIA problems (I hope)Alan Stern4-64/+28
Problems with NVIDIA's OHCI host controllers persist. After looking carefully through the spec, I finally realized that when a controller is reset it then automatically goes into a SUSPEND state in which it is completely quiescent (no DMA and no IRQs) and from which it will not awaken until the system puts it into the OPERATIONAL state. Therefore there's no need to worry about controllers being in the RESET state for extended periods, or remaining in the OPERATIONAL state during system shutdown. The proper action for device initialization is to put the controller into the RESET state (if it's not there already) and then to issue a software reset. Similarly, the proper action for device shutdown is simply to do a software reset. This patch (as1499) implements such an approach. It simplifies initialization and shutdown, and allows the NVIDIA shutdown-quirk code to be removed.

2011-11-18ktest: Check parent options for iterated testsRabin Vincent1-0/+16
Let's say we have "OUTPUT_DIR = build/${TEST_NAME}", and we're iterating a test. In the second iteration of a test, the TEST_NAME of the test we're repeating is not used. Instead, ${TEST_NAME} appears literally: touch /home/rabin/kernel/test/build/${TEST_NAME}/.config ... SUCCESS Fix this by making __eval_option() check the parent test options for a repeated test.
